Information on the throttling time period set for your particular account (as determined by Thomson Reuters) will be supplied as part of the confirmation letter sent upon entitlement of your Article Match Retrieve access.

All throttling messages begin with the text Request denied by Throttle server. Each message will also provide a reason for the denial.
